I had a building project until I added app_uart_fifo.c. The app fifo and uart flags are enabled in the sdk_config.h. This is a custom board. Now when I build I get the following errors:
Output/Debug/Exe/TagIt.elf section `.nrf_balloc' will not fit in region `UNPLACED_SECTIONS' region `UNPLACED_SECTIONS' overflowed by 28 bytes Output/TagIt Debug/Obj/app_error_weak.o: in function `app_error_fault_handler': undefined reference to `__start_log_const_data' Output/TagIt Debug/Obj/nrf_log_frontend.o: in function `nrf_log_frontend_dequeue': undefined reference to `__start_log_const_data'Build failed
Have you seen this thread, try following the approach given by RK.
Yes, adding the .nrf_balloc and then .log_const_data_app to the flash placement solved the remaining issues.
